How Bigelow Tea’s Signature Line Brings Together Flavor, Familiar Quality Ingredients, and Everyday Tea Rituals
Updated: January 16, 2026
At Bigelow Tea, crafting great tea starts with listening to how people actually enjoy their daily cup. Within the Bigelow Signature line, this black tea and two caffeine-free herbal teas are made with familiar ingredients and well-balanced flavors. These blends are designed to fit easily into everyday routines, whether that means starting the morning, taking a midday pause, or winding down in the evening with your favorite cup.
Below is an overview of three Signature line teas and the ingredients commonly associated with their flavor along with their functional characteristics.
Peak Energy™ Black Tea plus extra L-Theanine and Caffeine
Bigelow Peak Energy™ Black Tea plus extra L-Theanine and Caffeine is a bold black tea blend formulated for those who enjoy a rich cup with added lift. Black tea is naturally derived from Camellia sinensis leaves, which also contain L-theanine, an amino acid that has been widely studied in combination with caffeine.
Research published in 2021 in the Journal of Medicinal Food suggests that L-theanine may work synergistically with caffeine to benefit the brain and mood by increasing mental alertness. In this blend, additional L-theanine and caffeine are included to complement the robust flavor of black tea. Peak Energy™ is intended for people looking for a smooth, balanced tea experience as part of a morning or midday routine, not as a replacement for medical or clinical support.
Whispering Wildflowers™ Herbal Tea plus L-Theanine
Bigelow Whispering Wildflowers™ Herbal Tea plus L-theanine is a caffeine-free blend created to offer a calming, sensory tea experience. The tea features a floral blend of lavender, rose, passionflower, and butterfly pea flower, resulting in a naturally vibrant color and a delicate finish with a hint of sweetness.
Because L-theanine is not naturally present in herbal teas, it has been added to complement botanicals traditionally enjoyed as part of relaxation rituals. A 2020 study in Plant Foods for Human Nutrition journal suggests that L-theanine may promote a calming effect that may boost mood and help to manage stress and anxiety. This tea is designed to be enjoyed during moments of rest or reflection and is not intended to treat stress, anxiety, or other health conditions.
Ginger Honey Herbal Tea plus Zinc
Bigelow Ginger Honey Herbal Tea plus Zinc is a caffeine-free herbal blend featuring a spicy, zesty ginger-forward flavor balanced with a subtle sweet honey flavor. Ginger has long been used in culinary traditions and is commonly associated with digestive comfort. A 2022 study in Medicine suggests ginger may help support digestion, while zinc is an essential trace mineral involved in normal immune function and helps with healing says a 2023 study found in StatPearls.
This blend is intended to be enjoyed as part of a balanced lifestyle rather than for specific health outcomes.
As third-generation president and CEO of Bigelow Tea, Cindi Bigelow reflects on these Signature line offerings:
“These three teas from the Bigelow Tea Signature Line provide not only uncompromising exceptional flavor our consumers have grown to rely on, but also include ingredients and nutrients with functional benefits that help support a healthy lifestyle. I hope you love each beautiful cup of tea as much as I do.”
These blends reflect Bigelow Tea’s established approach to crafting teas that emphasize flavor and familiar ingredients, resulting in a cup each tea drinker can feel confident enjoying as part of their everyday routines. The Bigelow Signature line offers dependable options without making medical claims.
